But don’t feel like you missed it, because we’re offering the EAGLE workshop again! This coming Saturday from 12:00 to 3:00, Sean and I will be heading the workshop, where you’ll learn about what it takes to go from schematic to a shiny green (or red) printed circuit board. The main backbone for this process is EAGLE (Easily Applicable Graphical Layout Editor), a CAD (Computer Aided Design) program, which you will learn about in the workshop if you sign up today! Expect an email from Sean with more details, or if you just can’t wait to sign up, email him at smklaiber (at) gmail.com.
On another note, today is Heinrich Rudolf Hertz’s birthday! Happy Birthday Mr. Hertz!
It is 12 pm, October 29th, M5 opens its doors for engineering students to come expand their traits upon Chuck’s Xbee and Sean’s PCB design workshops.
Why Xbee? Well… XBee radios can be used to replace long wires in distributed electronic projects. These radios can replace serial communications links as well as pass digital and analog data. They are small (the size of a quarter), inexpensive, and can be configured to run a long time on a coin-cell battery. Applications include monitoring power consumption, instrumentation and control of distributed processes, investigation of network topologies and protocols, and cool gestural enhancement of electric guitars. Chuck’s hands-on seminar focused on digital and analog line passing and serial communications.
Across from the XBee workshop room, other students learn PCB layout and circuit prep for manufacture. By using Eagle Editor, Sean and his assistants, Edmar and Rodrigo, took students through the fundamental steps involving circuit layout/design and circuit preparation for manufacture.The coolest thing about this workshop is that students get the opportunity to materialize circuits that are products of their own ideas for their own purposes. The workshop allowed these engineering students to absorb the necessary specs behind the organization of circuit components before the design is sent for the ultimate PCB product.
We are back with an update on the design of partyduino. The team has made significant progress with the project and is getting ready for production. The design group finished their design by adding a low-pass filter to the output. Dan and Mat created a barebones version of the partyduino that closely represents the actual PCB. They ran into issues with the bootloader but overcame those issues swiftly and had the partyduino up and running by the end of the lab. While the other teams were working on design aspects of the circuit, Mike was preparing the parts list and datasheets that will assist in the design of the PCB. The datasheets will be used to gather the dimensions of each part and to help design the footprint of the parts to be out on the PCB.
The design of Partyduino is now in full gear! Partyduino is a circuit that was designed to make some funky beats and noises. The inputs to the arduino are two pots that determine which beats and noises are played. The arduino outputs a digital square wave that is altered by the low-pass filter and some caps, to a 3.5mm female stereo connector. Today, Joe the project leader, lead the design team in finalizing version 1 of the design for the circuit by adding a low-pass filter to the output signal. Dan is taking on the task of loading a bootloader to the ATMega 328 avr. Alden is on an alternative code that will generate two audio signals simultaneously. Mike is gathering all the parts needed for the pcb as well gahering all the datasheets for the parts. The datasheets will help when designing he actual pcb because the datasheet contains the dimensions for the respectful part.We’ll see you next week when
we start designing the pcb!!!
